Prins-Schmidt Cascade

Posted by naturalproductman on February 23, 2010

Jeffrey Aube and co-workers from the University of Kansas have recently published in Organic Letters on a tandem Prins/Schmidt reaction mediated by titanium tetrachloride to access the a 5,6,6-tricyclic ring system belonging to some alkaloids – cyclindricine and lepadiformine (diastereomers).
